I'd remove all widths. Now you say the whole table should be 1037 pixels (which is too wide for a fixed design). The first row should be 394 pixels. The second row should be 97 + 291 = 388 pixels. That doesn't add up at all.

You could make the whole table 100% or 75% or whatever. For the navbar you could also use a percentage. You can use pixels if you prefer, but 97 pixels isn't much on my standard sized screen. The other cells don't need a width.
